Description
Technical field
The present invention relates to heat treatment kiln technical fields, and in particular to a kind of roller kilns.
Background technique
Displacement room is the key equipment that process gas reaches requirement concentration in guarantee roller kilns, is arranged in roller kilns two
Gas displacement is completed in displacement room when material is into and out of roller kilns, to guarantee that furnace gas concentration is constant in end.With roller kilns
Cross-sectional width is more and more wider, and the width for replacing room also becomes wider than before, this has caused two problems: first is that with width
Increase, saggar is difficult to flatten after coming out of the stove；Second is that sealing difficulty is bigger after displacement room gate widths increase, it is easy to cause sealing not
Thorough problem.
Apparatus for leveling in existing roller kilns is to be stopped by leveling bar (block) moving up and down and let pass by roller
The saggar of stick carrying conveying, to realize the leveling of entanglement saggar.Such device has the disadvantage that since leveling bar is to move up and down
, it is flattened during decline and generates friction between bar and saggar, leveling bar and saggar can damaged, can also generate dust, and
And friction keeps entire flattening course stress complicated, has to the leveling effect, the reliability of apparatus for leveling and service life of material negative
Face is rung.Meanwhile flatten bar stop horizontal force when saggar all by with flatten the sliding part that moves up and down of bar undertake or
It is directly taken on by actuator, it is big to the abrasion of sealing element and movement parts to Structural strength calls height, it is necessary to maintenance is inspected periodically,
Have the defects that short service life, manufacture and maintenance cost are high.
For the leakproofness for improving displacement room gate, it generally can all be arranged in when flashboard is closed and compress holding down assembly for flashboard.
However it is existing hold down assembly there are mainly two types of, one is using multiple independent cylinders (generally more than ten) in different location pair
Flashboard is compressed, and for this structure there are at high cost, I& M difficulty is big, is difficult to control, the disadvantage of reliability difference,
And the service life under environment dusty is difficult to ensure；Another kind is that flashboard is mounted on lifting using complicated movement mechanism
In mechanism, make flashboard while can go up and down and translational motion, when realizing that flashboard is closed while can compress, this kind of structure presence
Structure is complicated, at high cost, and occupied space is big, the big disadvantage of production, I& M difficulty.
